 There are still many examples of using sickles to remove oxygen weeds, gardens, and weeds growing on the farms, but the sickle is focused on harvesting the crops, It is not easy and dangerous for beginners, and there are tired and inefficient jobs.

The electric lawn mowers are efficient, but there is a disadvantage that it is troublesome to carry a large and heavy lawn mowers in order to smooth the use environment or to use a small amount of lawn mowers. Therefore, manual lawn mowers are still necessary as a supplement for them.

The object of the present invention is to provide a golf club having a shape similar to that of an iron golf club, and aiming at standing by only waving lightly with one hand. As a means for solving this problem, the blade is lightweight and small, such as a disposable blade of a carter or a scraper, Make a blade mounting bracket for mounting the blade, drill three screw holes in the upper blade and bracket, fasten the upper blade and bracket by screwing them with screw bolts and nuts, and hold the shaft at an angle with the handle. If you swing the swing to hit the weeds on the ground from the right to the left like a golf swing, hold the handle with one hand with the right hand, And the tall grass like a long grass swings towards the ground, causing the aphid to fall on the ground Using the floor as a chopping board, the kitchen is cut in the form of cutting the vegetables with a knife.

Since the blade such as a sickle or a grass scissor has a disadvantage that it needs to be changed from time to time and it must be changed to the grindstones, in the present invention, it is extremely small and light like the scraper blade which is distributed at low cost compared with the polishing of the sickle, It is also convenient to use the high-strength disposable blades equipped to handle the work tool.

 As the effect of the present invention, first, it is convenient to stand and work with one hand. It is easy to not sit down with a cowgirl, and there is no hassle to grab a grass with one hand and pull a sickle with one hand. It is also different from the grass scissors that you should work with both hands.

The second is the so-called ax style that uses the centrifugal force of the head to beat the weeds, and the weed that is within the range of the arc that sweeps the ground in one swing is removed at once. have.

Third, the removal type of the grass is not the action of the pushing and pulling force like the saw or the sick, and the force is less.

Fourth, the size of the blades and the mounting base thereof is smaller than that of the conventional sickle blades, and is light in price and extremely inexpensive, so that there is a reduction in danger and convenience in storage and portable movement.

Fifth, when the sickle blade is faded, it is difficult to work and polish. However, since the blade of the present invention is replaceable and disposable, it can be replaced at the work site even when it is dry.

Sixth, in the public utility model publication 20-2010-0001731, a knife mounting bracket is inserted into a quadrangular box, the upper part of the barrel is used as a guard for the blade, and a blade is attached to the bottom part. The present invention is not limited to the use of a disposable knife. Therefore, the present invention is different from the design of the present application in the manufacturing method of a rectangular box, the mounting and weight of a blade, , The judge has not finished revising the specification while undergoing an aberration correction order on the grounds of minor incompatibility, and making the following utility model application, without judging the novelty or progressiveness during the examination. In the present invention, however, Sectional shape, and the method of mounting the handle shaft is such that the hosel is welded and then attached to the hosel, whereby the structure is extremely simplified, The cost of making a square barrel, the cost of making a hosel and the cost of welding it are reduced, and it is reduced to about one-tenth of the manufacturing cost, and the overall weight is also lightened, thereby improving the efficiency of use. The two designs are not homogeneous designs, and because they are homogeneous designs, they do not steal the design of others, so there is a novelty as a remarkable improvement.

Seventh, in the Utility Model No. 20-2013-0001311, the present invention is a structure in which the knife mounting pedestal is not a rectangular tube, but a knife is simply screwed on a cross section, but the method of mounting the shaft is that the hosel is placed on the pedestal, This is a structure in which the applicant, who is the applicant, made corrections to the decision rejected by the applicant during the examination by claiming that it could be made by anyone using the deficiency of written materials and exhibition precedent, In the present invention, the hosel for a shaft is not put, and the making of the shaft is omitted. The shank is made into a base 9 on a pedestal, the shaft is inserted into the shaft hole, 9], filled with an adhesive, to achieve the same fixing effect as that of welding, and the overall manufacturing cost It is possible to manufacture by hand, without welding equipment, because it is finished with cutting and bending, it does not require the production of a huge cost mold, and does not require the production and welding of hosel, Of the total cost, and is economically improved in cost-reduction production and manufacturing methods.

The components of the present invention include a shaft and grip (denoted by reference numerals 5 and 7) for a long handle and a detachable square blade (see FIG. 3) attached to a fastening 9 of a blade mounting bracket The nuts and bolts (Figs. 6 and 7) are inserted into the holes and fixed to the blade mounting base.

end. Blade mounting bracket ---

2 is a stainless steel plate having a thickness of about 4 centimeters and a length of about 13 centimeters. The flat portion is formed in a rectangular shape,

The opening of the blade 2 has a width of about 3 centimeters, so that only about 1 centimeter of the blade width is exposed, and the size of the opening portion is made smaller than the blade length so that a part of the upper and lower ends of the blade overlap with the base. The top and bottom are reinforced.

The inclined portion indicated by reference numeral 3 has a width of 4 centimeters and a length of about 4 centimeters, and is inclined at an angle of about 65 degrees relative to the ground.

(4 in Fig. 2) is inserted into the hole of the shaft.

The stainless steel pipe No. 7 is put into a hosel and fixed with an epoxy adhesive. The handle grip is made of a soft EVA material grip for use as an undercarriage. Stainless steel pipe with a diameter of 12.7 millimeters is enough to maintain the shaft strength of the golf body. It is 100 centimeters in length and can be held by a person standing upright. It tilts about 65 degrees from the ground, giving a comfortable angle naturally to the right hand without having to turn the person down.

6, 1, 2 and 3 of the bracket and the blade are to be connected by a bolt and a nut. As for the use hole, there is a hole of 7 mm in diameter so that the use hole of a commercially available scraper blade can use a bolt of 7 mm. Correspondingly make holes for general use.

I. Replaceable disposable square blade - Figure 3

This is a high-strength steel plate blade having a thickness of about 0.5 mm, which is commonly used as a cutter blade or a scraper blade. In the present invention, a blade having a width of about 33 millimeters and a length of about 111 millimeters , And a blade for scraper with three holes. The price of each piece is about 200 won, and it is very light and economical because the blade is hardly torn even if you cut grass or grass for about 10 weeks.

In one of these blades, it is extremely inappropriate to cut garden weeds, but it is reinforced on the blade support, and the power of the circular motion of the long shaft is added, and the function of 100 times .

All. Fixing bolts and nuts - Bolts and nuts to connect the blade to the base. Insert bolt from bottom to top and tighten with nut from above. When tightening from the top, it is convenient to have a handle, so use a butterfly nut among the nuts. Use a diameter of about 6 millimeters corresponding to the hole in the pedestal.

D. Mounting of shaft - Shaft 9 is placed on the shaft, and 8 mm of peg diameter 8 mm as shown in Fig. 9 is placed on the epoxy adhesive, which is then pushed into place with an epoxy adhesive therebetween.
